I didn't get any sense of consensus in the previous discussion (which
extended to at least Jan 2009) and several people there are rather more
expert in the MIPS variants than me. Perhaps someone would care to put
together a compilation of all the points raised and explain how the patch
addresses them or at least leaves things no worse off - in particular
detailing the circumstances (compiler options) under which the patch
results in any change to the code in glibc.
